Tire tread



FIG. 1 is a perspective view of the tire tread of my design;

FIG. 2 is a front elevation view of the tire tread of my design;

FIG. 3 is a side elevation view of the tire tread of my design;

FIG. 4 is a side elevation view of the tire tread of my design, taken from the opposite side of that shown in FIG. 3; and,

FIG. 5 is an enlarged, partial view of the tire tread of FIG. 1, as indicated by the break lines.

In the drawings, the evenly-spaced broken lines depict environmental subject matter that forms no part of the claimed design. The dash-dot-dot-dash broken lines define the claim boundaries. The tread pattern repeats uniformly throughout the circumference of the tire. 

CLAIM The ornamental design for a tire tread, as shown and described.
